The Company includes the underlying market condition stock options in the calculation of diluted earnings per share if the performance condition has been satisfied as of the end of the reporting period and excludes such options if the performance condition has not been met.

As of June 30, 2017 and 2016, the Company had securities outstanding that could potentially dilute basic earnings per share in the future, but these were excluded from the computation of diluted net loss per share for the three and six months ended June 30, 2017 and 2016, since their effect would have been anti-dilutive. These outstanding securities consisted of the following:



	June 30,
	2017	2016
Standard and market condition stock options outstanding	3,879,034	3,521,481
Restricted stock awards outstanding	44,538	77,540
RSUs outstanding	641,320	510,234
ESPP	22,604	27,670
